It’s a match. Your application – our precision sensors.

Zero-Flux technology - accuracy from mA to kA

HIOKI’s precision sensors are the best choice for highly accurate and stable measurements even at high currents up to 2000 A and high frequencies up to 4 MHz. Choose from our wide portfolio including clamp-type sensors and pass-through type sensors. These current sensors ensure reliable results even under harsh conditions, thanks to exceptional temperature stability and noise resistance - even when performing harmonic analysis at high switching frequencies. This is why they are trusted across industries like automotive, aerospace, and renewable energy.
